The Brazilian collided with Didier Ndong and was seen clutching his ankle before being carried from the pitch.

How long he will be sidelined is as yet unclear. ‘It is an ankle injury but we can’t say anymore until we see a scan,’ said Liverpool manager Jurgen Klopp after the match.

Liverpool fans will be keeping their fingers crossed but it looks like Coutinho could be out for a while. It’s a huge blow – the 24-year-old has arguably been Liverpool’s best player this season, scoring five goals and picking up the same number of assists.

But just how badly will his absence be felt?

We’ve taken a look at Liverpool’s record with and without Coutinho since the 2013/14 season, his first full campaign at Anfield, and it shows that Liverpool suffer when he’s not in the side.

With Coutinho playing some part in the game, Liverpool have a win percentage of 55%. When he’s not involved, that win percentage drops to 50%.

Looking at the number of points won with and without Coutinho over the same period, the picture is equally gloomy. Liverpool pick up 1.89 points per game with Coutinho but 1.7 without.

With Liverpool fighting for the Premier League title, the smallest of margins will probably decide who is crowned champion. History shows Liverpool aren’t as strong without Coutinho, and if he’s out for a while, it could ruin their chances.
